Which 3D Printed Materials Are Food-Safe? When using 3D printing to create eating utensils like plates, forks, cups, etc. The safety of these objects depends on the type of materials used in printing. There are a wide variety of materials that can are used for 3D printing, but most of them aren’t safe for use. Many factors like their chemical
3D printing now enables users to easily produce even practical kitchen utensils at home. The biggest risk with 3D printed cups or plates, however, is to ensure food safety, as even the smoothest prints have small cracks and gaps in which germs can accumulate and bacteria can thrive. If you want to create 3D-objects, which should come in contact
The main use for food-safe PLA filament is for printing 3D models that will contact food or drinks. These models might include a fruit bowl, candy dish, drink mug, or something else that touches something edible. True food-safe filaments, which have FDA approval, aren’t made by accident.

3D food printing may revolutionize the food and beverage industry – allowing creators to offer unique taste experiences and helping restaurants produce detailed designs faster. While there are no specific regulations for 3D-printed food, using ingredients that the FDA already recognizes as safe ensures the food is fit for consumption.

In this chapter, we describe the current 3D printing techniques applied to design food materials. They are classified according to the driving mechanisms of printing: inkjet, extrusion and heat source (powder layer binding). The deposition of liquid-based materials can be performed via extrusion and inkjet processes.
Short answer is: no. Long answer: Not even with coatings, as the resin can interact with the coating, apparently. And any reliable coating, might also be toxic for the reptiles and amphibians (especially when becoming damaged, or exposed to water or other solvents and enzymes). It's better to use it for casting in a more food-safe material.
